WATER-HEATER.

Specification of Letters Patent.

Patented June 26, 1916.

Application fil'ed March 11,1916. Seria1No.83,598.

To all whom it may concern:

Be it known that I, INGVALD K. OLsoN, a citizen of the United States, residing at Arnegard, in the county of -McKenzie and State of North Dakota, have invented certain new and useful Improvements in lVaterJleaters, of which the following is a specification.

This invention relates to water heaters and its object is to provide an improved device of this character particularly adapted v for use in heating water for stock in winter time, though it is to be understood that its use is not limited to this particular purpose but that it may be used for many other purposes, such as heating water for household use, for washing and in laundries or in smaller sizes may be used as a sterilization apparatus.

Further objects and advantages of the invention will be set forth in the detail description which now follows.

In the accompanying drawing: Figure 1 is a front elevation of a water heater constructed in accordance with the invention; and Fig. 2 is a longitudinal sectional view therethrough.

Like numerals designate corresponding parts in both of the figures of the drawing.

In carrying out the invention I provide a casing 5 having a doorway 6 at its front end that is closed by a door 7. This door has an opening 8 formed in its lower part, the size of which may be increased or diminished by moving a slide door 9 that is mounted in guides 10 carried by the door 7 The door 7 may be swung upon its hinges 11 in the usual and well-known way. Mounted upon the casing 5 is a tank 12, said tank having a bottom 13 and which bottom constitutes the top of the casing 5. Disposed within the casing 5 is a series of pipes, said pipes comprising a plurality of longitudinally extending upper horizontal pipes 1+1, a plurality of lower horizontally extending pipes 15, upper transverse pipes 16 and 17, lower transverse pipes 18 and 19, a plurality of vertical pipes 20 at the rear of the casing 5, which pipes areextended above the pipes 16 to form percolator pipes 21; a pair of front vertical pipes 22 disposed at opposite sides of the doorway opening and which pipes are extended through the bottom 13 of tank 12 and terminate a short distance above the bottom of said tank, as indicated at 23. An additional short vertical pipe 22 connects the transverse pipes 16 and 18 at the rear of the casing 5 and extends through the bottom 13 of tank 12 and terminates a short distance thereabove, as indicated at 23. The lower front horizontal pipe 19 is extended through the side wall of the casing 5 and is provided upon its outer end with a drain cook 24. A chimney 25 extends through the bottom 13 of the tank and projects a short distance above the top of said tank. The upper ends of the percolator pipes 21 are provided with horizontal discharge extensions 21*. The space between the pipes 14, 15, 20 and 22 constitutes a fire box 26 and the space below the pipes 15 constitutes an ash-pit 27. In operation, the tank 12 is filled to the desired level with the water to be heated and it is apparent that this water will pass into the various pipes at the points 23, 23 and with a fire maintained in the fire box 26 this water will be heated and continuously discharged through the percolator pipes 21 into the tank above the water level. The chimney 25 provides an escape for the products of combustion.

This water heater is particularly efiicient because the fire box is entirely surrounded by pipes containing water and the heat that passes from this fire box is conducted through a chimney which passes the body of water, so that the water is further heated and, in addition, the top of the fire box forms the bottom of the tank so that at this point a further heating of the water is had. The drain cock 24 provides means for draining all of the water from the heater to prevent freezing thereof when the device is not in use.

While the elements shown and described are well adapted to serve the purposes for which they are intended, it is to be understood that the invention is not limited to the precise construction set forth, but that it includes within its purview such changes as fairly come within the spirit of the ap pended claims.

Having described my invention, what I claim is:

1. A Water heater comprising a casing, a tank supported thereabove, a series of upper horizontal pipes and a series of lower horizontal pipes located within said casing, pipes connecting the upper and lower horizontal pipes, the latter lying in such spaced relation as to constitute a firebox between them, extensions from some of said pipes into the bottom of said tank to receive the water therefrom and vertical percolator pipes connected to said horizontal pipes extending through and discharging into said tank above the water level therein.

2. In a device of the character described, the, combination with a casing, a tank supported thereon, a chimney extending from said casing and through said tank to a point above the top of said tank, .a plurality of horizontally disposed upper pipes disposed within said casing, a plurality of horizontally disposed lower pipes in said casing;

upper and lower transverse pipes to which said horizontal pipes are connected, vertically disposed connecting pipes between saidvtransverse pipes some of which terminate inside the tank and near the bottom thereof and a plurality of percolator pipes extending upwardly through the tank and connected to some of the pipes within the casing and discharging into the tank at the upper portion thereof, the space between the upper and lower horizontal pipes c011- stituting a fire-box.

In testimony whereof I aflix my signature in the presence of two witnesses.
